Shane McGuigan knows Luke Campbell must defeat a ‘freak talent’ if he wants to become world lightweight champion on Saturday.

But the trainer is convinced his man has the talent and tenacity to stun pound-for-pound king Vasyl Lomachenko and relieve of him of his WBO World and WBA Super World titles at the O2 Arena.

And while most people are convinced Lomachenko will add that one to his collection, McGuigan believes Campbell will prove he can mix it with anyone.

McGuigan said: “We’re planning for the win. We know the magnitude of the upset, it would be the biggest upset in boxing, probably British boxing history since Donald Curry was beaten by Lloyd Honeyghan.

“We want it to come as a shock, we’re preparing for it and that’s what we’ve got in our mindset.
